Get signal names from numbers in Python

Question

Is there a way to map a signal number (e.g. signal.SIGINT) to its respective name (i.e. "SIGINT")?

I'd like to be able to print the name of a signal in the log when I receive it, however I cannot find a map from signal numbers to names in Python, i.e.:

import signal def signal_handler(signum, frame):     logging.debug("Received signal (%s)" % sig_names[signum])  signal.signal(signal.SIGINT, signal_handler) 

For some dictionary sig_names, so when the process receives SIGINT it prints:

Received signal (SIGINT) 

Answer 1

With the addition of the signal.Signals enum in Python 3.5 this is now as easy as:

>>> import signal >>> signal.SIGINT.name 'SIGINT' >>> signal.SIGINT.value 2 >>> signal.Signals(2).name 'SIGINT' >>> signal.Signals['SIGINT'].value 2
